SBR method intermittent biological treatment experimental device

Intermittent activated sludge treatment system is also called sequentially batch activated sludge processing system, and English is referred to as SBR process. The m--n feature of this process *** is that the degradation of organic pollutants and the hybrid hybrid fluid are integrated. Compared with the connected active sludge method, the process is simple. In the case, the expansion of the sludge is not produced. In a single aeration pool, nitrogen dehydration and phosphorus removal can be performed. It is easy to automatically control and handle water quality. This device is a teaching demonstration and dynamic experimental equipment for the SBR process. Through the hope of this experiment, the following goals are achieved:

Through this experiment, I hope to achieve the following goals:

1. Understand the characteristics of the SBR method system;

2. Deepen the understanding of the SBR method and the operation process.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. Treat water volume: 2 ～ 6L/h (average)

3. SBR: Stay time: 4, 6 ～ 13h

4. Second Shen Pond: Staying time: 4 ～ 1H

5. According to the local sewage data as the standard:

6. Design and water quality range:

1. M--n features:

1. Modular design, in the host module, all input and output ports are connected to the experimental board through the wire. Each experimental module has independent input, output, and public end. Users can facilitate expansion of their modules.

2. DC motors and relays and sensors use physical products, which improves the authenticity and practicality of the experiment.

3. Equipped with MCGS industrial control configuration software, you can intuitively conduct the basic instruction exercises of PLC, simulation experiments and physical experiments of multiple PLC practical applications. All experiments have configuration stick maps to track down. The actual application of the scene can quickly adapt to the actual operation of the scene through the tr--ning of this device.

4. Students here can understand the structure and principles of the inverter, the installation of the inverter and the use of the interface terminal, the communication of the inverter and the PC, the communication of the inverter and the touch screen, the setting of the frequency converter's own parameter, and the inverter in the inverter Settings and optimization of motor operation parameters (acceleration, deceleration, gearage, and torque control).

When the program is debugged, the touch screen can be used alone to control the frequency conversion system. The touch screen provides a graphic human -machine interface, which can change the frequency converter parameters and control the operation of the inverter.

5. Configuration monitoring tr--ning teaching based on the on -site bus: Through the on -site bus network, the tr--ning device (from the site) PLC and the m--n station PLC are 1: N communication. From the program of the PLC operation control object from the station, using the function of centralized monitoring of the industrial control network, the m--n station PLC can monitor real -time monitoring of any station PLC, which meets the requirements of industrial site control. Students independently complete the control of various tr--ning objects through PLC and perform real -time monitoring of configurations (1: 1 communication).
